TRACK-HINGE Fon SWING-Poms.

Specification of Letters Patent.

Patented Apr. 18, 1916.

To all whom ff/nay concern.'

Be it known that we, ALFRED D. WEST- MAN, IVILLIAM H. WESTMAN, JAMES N.RICHARDS, and Ross HUFF, citizens of Canada, residing at Chatham, in thecounty of Kent and Province of Ontario, Canada, have jointly inventednew and useful Improvements in Tracl Hinges for Swing-Poles, of whichthe following is a specification.

Uur invention relates to improvements in track hinge for swing pole; andthe objects of our improvements are to facilitate the quick removal oflitter from the stables without disconnecting the track, so far as weknow in swing poles at present in use the hanger carrying the littercarrier must be run out on the track before the pole can be swung aroundto deposit the litter where desired, after the litter carrier isemptied, the pole must be swung back to its former position before thecarrier can be returned into the stables.

Ne attain these objects in the manner as illustrated in the accompanyingdrawing, in which;

Figure l, is a top view of the hinge arm or projecting bracket and innerend of pole; Fig. 2, is a side view showing how the track is hung to thebracket and swing pole; Fig. 3, is a Side view of the upper bracedhanger of which Fig. 1, is a front view; Fig. 5, is a view from below,showing the relative position of the track to the projecting bracket andpole when the pole is straight out or swung either way as indicated bvthe arrows; Fig. 6, is a section through l-Q of steel casing J shown inFigs. 2 and 5 showing the sliding track within said casing.

Similar letters refer to similar Aparts throughout the several views.

Referring to Figs. 1 and 2, A is a hinge arm bracket projecting from andbolted to the wall N, over the doorway, and secured by braces I. Theswing pole B, of any desired length is attached at the inner end to thearm A by hinge plates E, and center bolt D, the outer end of pole beingheld up bv guy rods BI-M. hung from a ring L of hanger K in Figs. 3 and4l. The end of hanger K is vertically above the bolt D to keep the polelevel when swinging. The track F is attached to the bracket A .Copies ofthis patent .may he obtained for ve cents each, by ,addressing the andpole B by means of hangers C. C. on

which the hang-ers I-I of litter carrier run.

In some swing poles the track must be disconnected at or near the wallline when required to swing the pole, in others there are intricatesections between the stationary tracks which easily get out of order. Toovercome these diliiculties we have a flexible sliding track G,preferably composed of two pieces of thin steel springs attachedtogether at one end to the hanger C of pole B, the other end slidinginto a steel casing connected to either end of stationary track andbolted to the hanger C of the bracket A, thus forming a continuoustrack. When the pole is at a right angle to the building yand the trackin a straight line, the loose end of flexible sliding track is partly inthe steel casing as shown by slot O Fig. 2, leaving a space P Fig. 5;this allows the end of flexible sliding track to recede and slide overthe bolt astening the casing to the hanger when the pole is swung eitherway. This enables the carrier to be moved around the corners and dumpedwhere desired and returned into barn without disconnecting the pole,whether it be straight out or parallel with the wall of building or anyangle between these points.

As considerable variation is possible in the details of construction ofour improved device without departing from the spirit of our invention,we do not intend to limit ourselves to the specific form herein shownand described.

What we claim as new in connection with a swing pole track and desire tosecure by Letters Patent, is

vl. The combination of a flexible sliding track with a steel casing aspart of the track.

2. The combination of a projecting bracket, with a flexible slidingtrack and a steel casing as part of the track.

3. 4The combination of a braced hanger with a projecting bracket, allexible sliding track and a steel casing as part of the track.
